Did you have random university assigned roomies? That's what I did freshman year cause I didn't want to live with my high school friends and end up hating them. I ended up in a quad, but we all got along, and two of stuck together for two years after that.

Leaving alarms going off is obnoxious, especially if it's on the annoying buzzy thing. (I always put mine on the radio so I don't have to wake up to a headache.) There was one time the girl in the room next to us left for the weekend but left her alarm on. It was going off for several hours before the RA finally decided it warranted going in to turn it off.
